I have not written all methods. As far your exam is concerned, it may be sufficient. Soil conservation is the preventing of soil loss from erosion or reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination.
There are many ways for conservation of soil:
1) Contour ploughing
2) Mulching
3) Strip Cropping
These are parts of agronomic practices.
1)Contour ploughing-Contour Plowing involves plowing grooves into the desired farmland, then planting the crop furrows in the grooves and following the contours. It a very effective way for farmland on slopes to prevent run off improve crop yields.
2) Mulching-The bare ground between plants is covered with a protective layer of organic matter like grass clippings, straw, etc.It mainly helps to retain soin moisture.
3) Strip cropping-Crops may be cultivated in alternate strips, parallel to one another. Some strips may be allowed to lie fallow while in others different crops may be sown.Various crops are harvested at different intervals. This ensures that at no time of the year the entire area is left bare or exposed.
Hope it helps!!
